Capnograph Sidestream CA10S

What Is a Sidestream Capnograph?

The CA10S is a sidestream capnograph ? an instrument that continuously samples expired gas from the patient’s airway through a fine sampling line and measures the carbon dioxide concentration in real time. The resulting waveform (capnogram) and numerical EtCO2 value are displayed on screen, providing immediate, non-invasive confirmation of airway patency, tube placement, and adequacy of ventilation. Sidestream capnography is suitable for both intubated and spontaneously breathing patients using nasal sampling cannulas.

Clinical Applications

EtCO2 monitoring is the gold standard for confirming endotracheal tube placement after intubation ? it is more reliable than auscultation and chest X-ray for immediate confirmation. It is also used to monitor the adequacy of ventilation during procedural sedation, general anaesthesia, and post-operative recovery; to detect oesophageal intubation (absence of CO2 waveform); to monitor respiratory rate and detect apnoea; and to assess return of spontaneous circulation (ROSC) during CPR, where rising EtCO2 is an early sign of cardiac output recovery.

Sidestream Sampling Advantage

Sidestream capnographs aspirate a small gas sample (typically 50?150ml/min) from the breathing circuit or via a nasal cannula and analyse it in the main unit. This design is lightweight, compatible with both intubated and non-intubated patients, and suitable for MRI environments (with appropriate accessories). The CA10S connects to standard 22mm breathing circuits and nasal sampling cannulas.
